The development of surface-immobilized molecular redox catalysts is an emerging research field with promising applications in sustainable chemistry. In electrocatalysis, paramagnetic species are often key intermediates the mechanistic cycle but inherently difficult to detect and follow by conventional situ techniques. We report a new method, operando film-electrochemical electron resonance spectroscopy (FE-EPR), which enables studies electrocatalysts. This technique radicals formed during...
Abstract Strong interest exists in the development of organic–inorganic lead halide perovskite photovoltaics and photoelectrochemical (PEC) tandem absorber systems for solar fuel production. However, their scalability durability have long been limiting factors. In this work, it is revealed how both fields can be seamlessly merged together, to obtain scalable, bias‐free water splitting devices. For purpose, state‐of‐the‐art cesium formamidinium methylammonium (CsFAMA) triple cation mixed...
Abstract Electrolyzers combining CO 2 reduction (CO R) with organic substrate oxidation can produce fuel and chemical feedstocks a relatively low energy requirement when compared to systems that source electrons from water oxidation. Here, we report an anodic hybrid assembly based on (2,2,6,6‐tetramethylpiperidin‐1‐yl)oxyl (TEMPO) electrocatalyst modified silatrane‐anchor ( STEMPO ), which is covalently immobilized mesoporous indium tin oxide meso ITO) scaffold for efficient alcohol (AlcOx)....
Abstract Solar‐driven reforming uses sunlight and a photocatalyst to generate H 2 fuel from waste at ambient temperature pressure. However, it faces practical scaling challenges such as dispersion recyclability, competing light absorption by the solution, slow reaction rates low conversion yields. Here, immobilisation of noble‐metal‐free carbon nitride/nickel phosphide (CN x |Ni P) on textured glass is shown overcome several these limitations. The 1 cm CN P panels photoreform plastic,...
A triphasic photocatalytic reactor employing a mesoporous carbon nitride photocatalyst and aerobic O2 was assembled to operate under continuous flow conditions. This design allows for facile downstream processing reusability in multiple cycles. The selective oxidation of alcohols amines chosen demonstrate the applicability performance advantage this approach compared that conventional batch photochemistry. precious-metal-free system operates benign reaction conditions (visible light, low...
The development of efficient catalysts is a highly necessary but challenging task within the field environmental water remediation. Single-atom are promising nanomaterials this respect, in-depth studies encompassing class remain elusive. In work, we systematically study degradation gemfibrozil, persistent pollutant, on series carbon nitride photocatalysts, investigating both effect (i) catalyst textural properties and (ii) metal single atoms contaminant degradation. Tests in absence result...
Efficient catalytic methods for the trifluoromethylation of (hetero)arenes are particular importance in organic and pharmaceutical manufacturing. However, many existing protocols rely on toxic reagents expensive or sterically hindered homogeneous catalysts. One promising alternative to conduct this transformation involves use carbon nitride, a non-toxic photocatalyst prepared from inexpensive precursors. Nonetheless, there is still little understanding regarding interplay between...
Existent rigid unit mode (RUM) models based on rotating squares, which may explain the phenomenon of negative thermal expansion (NTE), are generalized so as to assess NTE potential for novel systems made from rectangular or rhombic units. Analytical area coefficients (CTE) these innovative networks derived in an attempt determine optimal geometrical parameters and connectivity maximum NTE. It was found that all exhibit NTE, extent is determined by shape elemental units (side lengths ratio...
Abstract Single‐atom catalysts hold the potential to significantly impact chemical sector, pushing boundaries of catalysis in new, uncharted directions. These materials, featuring isolated metal species ligated on solid supports, can exist many coordination environments, all which have shown important functions specific transformations. Their emergence has also provided exciting opportunities for mimicking metalloenzymes and bridging gap between homogeneous heterogeneous catalysis. This...
Abstract Cross‐coupling reactions are of great importance in chemistry due to their ability facilitate the construction complex organic molecules. Among these reactions, Ullmann‐type C−O coupling between phenols and aryl halides is particularly noteworthy useful for preparing diarylethers. However, this reaction typically relies on homogeneous catalysts that rapidly deactivate under harsh conditions. In study, we introduce a novel heterogeneous catalyst reaction, comprised isolated Cu atoms...
